Abstract

In this work, the possibility of using silicone resins to construct a breast cancer training model is examined. A locally available resin that is investigated is RTV 585. The curing agent was varied at different concentrations i.e. 1.0, 1.5, 2.0 and 2.5 phr. An organometallic (tin) catalyst was utilized as a curing agent in the present work. It was found that the curing agent significantly improved the elastomer strength by enhancing the cross-link density of the resulting cured specimens. Furthermore, the modulus as a function of time indicated that the resulting elastomer might take up to 2 weeks at room temperature to render a complete development in the specimen mechanical properties. Elevated temperature was found to significantly reduce the gel time of this silicone resin and the temperature-dependent gelation process of the resin can be well predicted using the Arrhenius model. This study paves the way for the further improvement in the fabrication of the breast model final products based on silicone elastomer
